Embodiment Construction

[0058] It is proposed to combine Wudongde Hydropower Station 10 # The actual case of the civil engineering construction site of the water diversion tunnel body will further illustrate the operation process of the present invention. The places where safety signs can be arranged on the construction site are divided into 6 areas, as shown in Table 1.

[0059] Table 1 Construction site zoning

[0060]

[0061] The reading area α ranges from 1 to 6.

[0062] Step 1: First, use the Tobii Glass eye tracker to collect the eye movement behavior data of the workers, randomly organize 35 workers on the construction site as volunteers to conduct experiments, and collect the total visits of the areas of the construction site and the gaze points in each area Data such as time, fixation point, fixation times, left pupil diameter of each operator, right pupil diameter of each operator, eye movement event duration, etc. The description of the collected data is shown in Table 2.

Abstract

The invention discloses a method for automatically determining a layout area of a safety sign at a construction site. In the method, the eye movement indicators such as the visit time, fixation times, pupil diameter, regression times and the like of operating staff to each area at a construction site are captured in real time by an eye tracker, main concerns of the operating staff are automatically found out, and the layout area of the safety sign is determined. According to the invention, the rationality of the layout area of the safety sign at the construction site can be improved, the precaution ability of the operating staff is thus improved, and the occurrence of accidents is reduced or avoided.

Description

technical field [0001] The invention relates to a method for automatically determining the layout area of ​​safety signs on a construction site, and the method is mainly used to improve the rationality of the layout of safety signs on the construction site. Background technique [0002] The layout of safety signs on the construction site is an important guarantee for safe construction. The state has issued relevant standards such as "Safety Signs and Guidelines for Their Use (GB 2849-2008)", which clearly stipulates the signs used in different construction scenarios. Color, shape, model, installation height and usage requirements. However, the reasonable area for the layout of sign boards has not been specifically given. The rationality of the layout area for sign boards on the job site needs to be verified, and it is still unclear whether the layout area meets the psychological characteristics of the operators. In the 1980s, with the development of eye-tracking technology,...
